Hey Ole,
this is frequently asked, if you ask me, I would say, this. Others answered here and here
There is no upgrade for the Journeyman, it’s the biggest machine that Onefinity offers so far, but since it is a CNC machine that is open on the front and on the rear, you can do projects of inifinite length by having the machine process the workpiece step by step (search for ‘tiled’). The workarea width of Journeyman is 1220 mm.
